[PATCH 0/6] Improve tag checking in fsck and with transfer.fsckobjects

[Johannes Schindelin <schindelin@wisc.edu>]

This patch series introduces detailed checking of tag objects when calling
git fsck, and also when transfer.fsckobjects is set to true.

To this end, the fsck machinery is reworked to accept the buffer and size
of the object to check, and for commit and tag objects, we verify that the
buffers end in a NUL.

This work was sponsored by GitHub.

Johannes Schindelin (5):
  Refactor type_from_string() to avoid die()ing in case of errors
  fsck: inspect tag objects more closely
  Add regression tests for stricter tag fsck'ing
  Refactor out fsck_object_buffer() accepting the object data
  Make sure that index-pack --strict fails upon invalid tag objects
